Nothing can breathe
The river enters Delhi alive and leaves it without oxygen. Twenty-two kilometres of it are inside the city, under two per cent of its length, and they carry most of its pollution load.

Above normal
Above normal is not the same as illegal. What floods the drains is a single day above 100mm, and there have been two.

Below season
A detection is a thermal anomaly, not a confirmed fire. In Punjab and Haryana in October it is very often crop residue rather than forest.

Each reading is dated on its own page.
So we take them to the water.
What we do
Four kinds of work. Not four departments.
Journeys
You cannot teach a river from a photograph. So we go — two hours into a landfill, a few days into a forest, most of a week in a village, twelve days from Yamunotri to Agra. A journey is the part of the argument that has to be walked.
Projects
In the order they take up our week.
A learning lab on five acres. Day visits, short courses, internships and stays.
Over 70 butterfly parks and over 20 herb gardens across Delhi NCR.
Over 3,000 girls and boys in thirteen years. Over 200 came back as peer leaders.
Volunteering and a fellowship, nationwide. Ten thousand volunteers a year, and over 300 youth groups.
With EMpower: over 50 adolescent girls from Jagdamba, on agency and decision-making, since 2017.
Curriculum and action projects on food and sustainability, in Delhi NCR government schools.

All the eventsAbout Swechha / Since 2000
Swechha means, roughly, of one’s own free will.
Who we are
Swechha started in 2000 as We for Yamuna — a collective response towards growing apathy towards one of the most polluted rivers of the world. Since then it has been an organisation dedicated to enabling ourselves and others around us to Be the Change, in making a visible difference to the environment, both physical and social. The mission is one sentence: to inspire, create and support a just, equitable and sustainable society, for everyone and forever. Three words hold the work — Education. Environment. Enterprise.
2000
We for Yamuna. No funding, no office, one stretch of bank.
2004
The first Yamuna Yatra walks the river from Yamunotri to Agra.
2008
One of six stories on CNN’s Be the Change, reported weekly for a year.
2016
City to countryside. Land, water, livelihoods and the farm.
Now
Still showing up. A monitoring feed, and the records nobody else has.

Out of the Yamuna
Green cover, in one Vasant Kunj park, over a decade
Green infrastructures, across 100+ schools
A real place, an hour and a half from Delhi
Nothing grew here. Five acres of barren ground is now a food forest and a working farm — and a classroom that school groups come to for a day, or stay in overnight.
What grows there now
Over 5,000 trees · 20 cows · poultry · a native nursery of twenty thousand saplings · vermicompost · hydroponics · an apiary · a butterfly garden · organic farming · mud houses · permaculture prototypes

A different organisation
Upcycled goods made from what the clean-ups pull out. It has its own site, its own accounts and it pays its own way. It is not a Swechha programme.
Visit the shop (opens in a new tab)Four things accumulate here whether or not anybody writes a post: the daily readings, the orders that follow them, the things you can do about them, and the paper since 2000.
Updated every hour
Air, river, heat, fire and rainfall, each with its monitor and its hour. Every day’s readings keep their own address after they stop being today’s.
9,400 days on file since 2000
Every source named
Every source behind the readings, with its cadence, the date it was last drawn, and whether it is running.
Nothing here is unsourced
Evergreen
Compost, a balcony air-detox garden, a school waste audit, a river walk you can run without us. Written to be used, not to be admired.

The monitoring and the archive are the two things nobody funds. They are the two things that outlast us.
From 500 rupees a month, recurring. It pays for journeys schools cannot fund, gardens still being planted, and an archive that will not scan itself.
Clean-ups, garden builds and scanning days in Delhi. Turn up once or turn up every month.
Schools, companies and researchers. Bring us a ward, a river stretch or a cohort.
